After several months of research and deliberation I just ordered a MII suspension today from CPP. It's a TCI unit with air bags, power rack, 2" drop spindles, sway bar and they throw in free shipping, an adjustable brake proportioning valve, power steering hoses and stainless brake hoses. Total came to $1894. I evaluated all of the options (and I mean all) but for price and completeness I couldn't pass this up. It also has the boxing plates which makes a difference to me. Time is scarce, the less of it that I spend sourcing/making parts the better.
